Described how calcium release channels and calcium pumps work and how mutations in these proteins cause inherited muscle diseases
An interdisciplinary researcher who developed our understanding of normal and abnormal muscle function
As a newly independent investigator in 1969, Dr MacLennan embarked on the isolation and characterization of a Ca2+ ATPase from a then obscure membrane system, the sarcoplasmic reticulum (SR). He went on to describe the mechanism of action of the Ca2+ pump, the structure and function of many other muscle proteins involved in Ca2+ signalling in muscle, the genes encoding these proteins, and the genetic basis for muscle diseases caused by mutations in these genes.
These earlier studies allowed Dr. MacLennan to identify patients who are susceptible to malignant hyperthermia (MH) or to exercise-induced sudden cardiac death. MH Patients are at risk of fatal reactions to anaesthetics – if identified, they can be treated with safe anaesthetics.
Key Facts
Defined the functional characteristics of several novel proteins
Discovered the gene mutation that leads to Brody Disease
Developed the technology required to carry out expression and site-directed mutagenesis of calcium ions located in the SR
Developed the diagnostic test for MH mutation in swine and, as a result, contributed to significant economic benefit to the swine industry
Held multiple patents
The Institute of Scientific information included him in a small group of scientists whose work has been proven to be “highly cited”
Professional timeline
Impact on lives today
Dr. MacLennan’s career is a testament to the benefits of scientific excellence, passion, and commitment. For over 40 years, he endeavoured to understand the structures of function of the SR and calcium ions. In time, Dr. MacLennan's efforts led to the definition of the protein components of the SR and to understanding the structure and functions of the Ca2+ pump. His experimental and conceptual breakthroughs have enhanced basic knowledge, improved patient care and facilitated economic savings in the agricultural industry.
